note 116302 added to function.array-unique

Create multidimensional array unique for any single key index. e.g I want to create multi dimentional unique array for specific code Code : My array is like this, <?php $details = array( [0]=>array("id"=>"1","name"=>"Mike","num"=>"9876543210"), [1]=>array("id"=>"2","name"=>"Carissa","num"=>"08548596258"), [2]=>array("id"=>"1","name"=>"Mathew","num"=>"784581254"), ); ?> you can make it unique for any field like id, name or num. I have develop this function for same : <?php function unique_multidim_array($array, $key){ $temp_array = array(); $i = 0; $key_array = array(); foreach($array as $val){ if(!in_array($val[$key],$key_array)){ $key_array[$i] = $val[$key]; $temp_array[$i] = $val; } $i++; } return $temp_array; } ?> Now, call this function anywhere from your code, something like this, <?php $details = unique_multidim_array($details,'id'); ?> Output will be like this : <?php $details = array( [0]=>array("id"=>"1","name"=>"Mike","num"=>"9876543210"), [1]=>array("id"=>"2","name"=>"Carissa","num"=>"08548596258"), ); ?> ---- Server IP: 72.52.91.14 Probable Submitter: 202.131.119.122 ---- Manual Page -- http://php.net/manual/en/function.array-unique.php Edit -- https://master.php.net/note/edit/116302 Del: integrated -- https://master.php.net/note/delete/116302/integrated Del: useless -- https://master.php.net/note/delete/116302/useless Del: bad code -- https://master.php.net/note/delete/116302/bad+code Del: spam -- https://master.php.net/note/delete/116302/spam Del: non-english -- https://master.php.net/note/delete/116302/non-english Del: in docs -- https://master.php.net/note/delete/116302/in+docs Del: other reasons-- https://master.php.net/note/delete/116302 Reject -- https://master.php.net/note/reject/116302 Search -- https://master.php.net/manage/user-notes.php
